Muck Boots
All Muck Boots are 100% waterproof keeping feet warm, dry and protected in harsh weather and messy working conditions. The secret - Muck Boots, self-insulating, waterproof CR-foam shell construction. The CR-foam bootie material acts as a "neutral medium" between inside and outside temperatures. Naturally lightweight, buoyant and very comfortable, the material keeps the foot and lower leg warm and protected in cold and wet conditions.
